BRICKMAKING MACHINE.

Application filed. November 18, 1924. Serial No. 750,706.

To all whom it may concern Be it known that I, DAVID F. Snorn, a citizen of the United States, resldmg at Portland, in the county of Multnomah and the State of Oregon, and havingmy postoffice address at 1396 VVlStQIlEL Street, 1n said city and State, have invented anew and useful Improvement in Brickmaking Ma chines,'of which the following is a specifica tion.

My invention relates to brick making ma- 7 chines and is more particularly adapted for use in the makin of the so called cement types.

bricks, of both the. common and the face-d In the invention herein I have made in'iprovements in the machines now in common use the same being more specifically applied to the end closure. In my invention I have provided an end closure adapted to being held in hinged relationship with a counter balance wherein the end closure is adapted to an end movement as well as to an up and down movement. Further novelty resides in a hinged closure that is adapted to cover the end closure when the same is depressed for its full downward movement, but that 1311013 hinged down if a stop is interposed in the path of the same where a coverage is not necessary; this is essential as a time saver to the workman IVith these and incidental objects inview the invention consists in certain novel features of. construction and combination of z..ts, the essential elements of which are l set forth in the appeuded'claims and a preferred, form of embodiment of which ishereinafter shown with reference to the drawing which accompany and form a part of this specification.

device of the end closure.

Fig. V is a front elevation-of the machine showing the end closure'in down position and covered with the hinged closure. Y i

Fig. VI is a detached view of the locking Like reference characters refer to like parts throughout the several views.

. A structural frame 1 having a bed struc time, and a tamping bar 3 to which the tamping head 4 is attached, forms the main members of the machine. y

The end closure 5 is adapted to placement the stop for the end of the bricks to be formed. It is desirable that an end movement be imparted to the machine; to acc01n plish this object the closure has lugs 6 and 7 secured thereto and into which the rod 8 is made secured by screw end, having nuts attached thereto or by other suitable means. Arms 9 having a counterbalance 10 are supported and pivoted about the pin 11. The pin 11, is supported by link 12 which is secured to the cross rod 13 supported within the frame structure of the machine. The arms 9 and 9 are here shown as two in number and the same are held in alignment and upon the front of the machine and to form in relation with each other by means of the spreader rod 14. Openings are provided in the arms for a working fit aboutthe rod 8, to permit ofthe end movement of the end closure inrelation with the arms. The closure 5 has a lug 15 uponone end of the same and is held in fixed position upon the closure by rivets 16, or by "other suitable fastenings. Atapered'pin 17 is secured to the side member of the machine and an opening through th e'lug permits ofthe tapered pin passing. therethrough 'to securely position one end of the end closure. A ledge 18 forms a suit I able guide and support to maintainthe end closure 5 in horizontal alignment. To lock the end closure in position after the same has been positioned the handled member 19 is held in hinged relationship within the lug 20 by means of the pin 21. The pin 21 has a square head 22 adapted to engagement with the spring member 23 thatis secured to the end closure by suitable fastenings 24:. The spring 23 affords substantial pressure being supplied against the head of the pin and as the handle is rotated about ahorizontal pivotthe pin 21 is also rotated be cause the handle member is secured thereto and in fixed relation therewith. This rotates the head 23 of the pin, and the flat surface of the head tends to position the pin when the same contacts with the spring 23. The spring maintains the handle in and out of engagement.

In certain operations of the machine it is required to lower the end closure only a part of the way down as is shown in Fig. III, while in certain other operations it is required that the same be lowered to the full low position as is shown in the dotted lines of Fig. I. When the end closure is lowered but part way the hinged cover remains in placement, but when the end closure is lowered to the full low position the hinged cover is actuated and covers the end closure to prevent aggregates and other materials from engaging upon the end closure, while in the lowered position. The hinged cover iscomposed of two parts 27 and 28, the up per, or 27 is secured to the machine frame by suitable 'fastenings, and the lower or 28 is hinged thereto by suitable hinges 29. The lower or 28 is held in a raised position by means of the spring 30. To facilitate the easeof operation and to eliminate the shock due to the lowering of the end closure, I have provided a guideway having a rise 33 in its periphery upon which the follower 31 engages in its travel. The arms 9 being supported about the link 12 permits of the forward movement of the closure plate and the contact of the follower with the rise in the periphery tends to stop the shock incident to the lowering of the same. lVhen it is desired that the end closure be lowered for a part of its total travel a stop 36 is interposed within the path of the arm and arrests the travel of the same. The stop 36 is secured to the frame structure of the machine as shown at 39, and is secured thereto by suitable fastening means as shown at 37. To place the stop in operative position, the stop 36 has a lug 38 that engages the frame structure 39, and maintains the stop 36 in fixed position. When it is desired to lower the end closure for the full downward travel of the same the stop is placed in position as illustrated in Fig. 11 and in the downward travel of the arms 9 the cross bar engages the trip 35 secured to the lower member 28 and since the same is secured to the lower member 28 the same is caused to rotate about the pins of the hinges 29 and to cover the end closure when the same is depressed to the full downward stroke. In doing so additional tension is placed in the spring 30 and as soon as the end closure is raised by manual or other manipulation the spring returns the lower cover 28 to its raised or normal position.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all. coming within the scope of the claims which follow.

What I claim is:

l. A new and improved brick making machine, comprising a frame structure, arms held in suspended relationship with the frame and adapted to being lowered, a counter balance and an end closure supported by the arms, and a hinged cover adapted to bein actuated when the arms are depressed to the full lowered position.

2. A new and improved brick making machine, comprising a frame structure, arms held in suspended oscillating position with relation to the frame, means adapted to position the arms when lowered partially, counterbalancing means and an end closure secured to the arms, the end closure adapted to an endwise movement in relation to the arms, locking means adapted to position the end closure and maintain the same in locked position, and means adapted to cover the end closure when lowered to an extreme low travel of the same.

3. A new and improved brick making machine, comprising a frame structure, arms adjustably supported within the frame, a counter balance and an end closure adjustably connected to the arms, and means for predetermining the stop position of the arms when lowered.

4 A new and improved brick making machine, eomprising a frame of structural material, arms adapted to being raised and lowered, maintained within the frame, counterbalancing means adapted to the arms, an end closure, having a locking means, secured to the arms and adapted to lateral movement in relation therewith, and means adapted to being actuated by the lowering of the armsto cover the end closure when lowered to primary position.
